Abstract

L'invention concerne des techniques de mise en rapport d'indicateurs de qualité de voie (CQI). L'activité de données au niveau d'un récepteur peut être déterminée et la mise en rapport de CQI par le récepteur peut être ajustée sur la base de l'activité de données déterminée. Dans un mode de réalisation, la mise en rapport de CQI peut être autorisée pendant une fenêtre temporelle entourant chaque arrivée de paquet attendu pour une transmission périodique ou quasi périodique, et peut être suspendue à l'extérieur de cette fenêtre temporelle. Dans un autre mode de réalisation, la mise en rapport de CQI peut varier sur la base d'une rétroaction ACK/NACK. Dans un mode de réalisation supplémentaire, les CQI peuvent être envoyés à un premier débit lorsque l'activité de données n'est pas détectée et à un second débit plus rapide que le premier débit lorsque l'activité de données est détectée. Dans un autre mode de réalisation, les CQI peuvent être envoyés uniquement pendant des périodes de transmission discontinue (DTX) ON lorsque l'activité de données n'est pas détectée, et peuvent être envoyés pendant les périodes DTX ON et OFF lorsque l'activité de données est détectée.
